DUAL ACCUMULATOR LID FOR VALVE REGULATED LEAD-ACID ACCUMULATORS WITH GAS EXHAUSTING SYSTEM, LOCATED IN THE PRIMARY LID

摘要

The utility model finds application in the production of unattended accumulators used in fixed power supply stations, known as stationary or VRLA (valve regulated lead-acid) accumulators. The dual accumulator lid (4) for valve regulated lead-acid accumulators with gas exhausting system , located in the primary lid, includes primary and secondary lid (2 and 3) and the secondary lid (3) provides a fail-safe release of gas and maintenance of fixed production value of the work cavity (16). The secondary lid (3) prevents gaps occurring in the working cavity (16) between the secondary lid (3) and regulatory pressure valve (11) that limits the gas compression in the cage for collection of gas (10). A spark (flame) arrestor (9) keeps the position of the primary (2) and secondary (3) lid unchangedto one another and prevents retention of gas in the ducts (5 and 6) and the hose for gas release (14), which ensures the maintenance of the internal pressure in the cells (13) at a constant level between 55-155 mbar during operation of the accumulator (1). The dual accumulator lid comprises and:• at least two fixing teeth (7) on the secondary lid (3),• sockets for fixing teeth (18) on the primary lid (2) corresponding to the fixing teeth (7),• at least two ducts for opening (15) of the fixing teeth on the primary lid (2),• at least two ducts for gas release (5 and 6) arranged on the primary lid (2) - a duct (5) on the side of the terminal (17) and a duct (6) on the rear side,• connecting hose (14) made ??of flat, solid material, which does not twist and not flex.
